Taco Bell has released a statement since the photo was posted, saying:

“Nothing is more important than the safety of our customers and team members and we have strict food handling procedures and zero tolerance for any violations. When we learned of the situation we immediately contacted this restaurant’s leadership and, although we believe it is a prank and the food was not served to customers, we are conducting a full-scale investigation and will be taking swift action against those involved.”

The restaurant in question is believed to be in California.
